Public bug reported: With the change of https://review.openstack.org/#/c/465160, NUMA related features like CPU pinning, hugepages, and realtime are now explicitly disabled when using libvirt driver with `virt_type=xen`, and compute hosts with libvirt/xen driver are filtered out with NUMATopologyFilter.
We should test and make clear which of the NUMA related features can be supported by libvirt/xen driver and enable them with documents. Note: Remenber to update at least these documents when they are enabled. https://docs.openstack.org/nova/pike/admin/huge-pages.html https://docs.openstack.org/nova/pike/admin/cpu-topologies.html ** Affects: nova Importance: Undecided Status: New -- You received this bug notification because you are a member of Yahoo!
